What Are Comps in Real Estate?
Published by Cash Flow Deals · Last updated 2026-08-04 · Published and reviewed for compliance by Camilo Palacio, a Florida Licensed Realtor
Comps, short for comparable sales, are recently sold homes similar in size, condition, and location to yours. Appraisers use them to help you understand what your house is actually worth right now, rather than what you hope it's worth. Only closed sales count as true comps. Homes still for sale and pending sales are reference points, not comps.
| Factor | Pulling Comps Yourself | Working With a Licensed Professional |
|---|---|---|
| Data access | Public records and sites like Zillow or Redfin, updated on their own schedule | MLS access with real-time closed sale data, off-market comparables, and pending activity |
| Adjustments for differences | Rarely adjusted for lot size, condition, or upgrades in a structured way | Line-by-line dollar adjustments for square footage, condition, age, and location |
| Use in a real offer | Good for a ballpark number | Required for a loan-backed offer, since a lender's appraiser must independently confirm value |
Comps vs. Comparables vs. Active Listings
Comps, short for comparable sales, are homes that already closed, meaning the sale is done and the price is a real, agreed-upon number. That's the whole point of a comp: it reflects what a buyer actually paid, not what a seller hoped to get. Active listings are asking prices, not sale prices, so they show what sellers want, not what the market will bear. Pending sales sit in between: a price has been agreed to, but it hasn't closed yet and could still change. An appraiser's report leans on closed comps almost exclusively. An agent's pricing conversation might reference active and pending listings too, but only as context, not as the core evidence.
How Comps Get Chosen
A good comp is close in three ways: location, size, and time. Location usually means the same neighborhood or a comparable one nearby, not just the same zip code. Size means similar square footage, bedroom and bathroom count, and lot size, since a 1,200 square foot home and a 2,800 square foot home rarely tell you much about each other even if they sit on the same street. Time means recent. Exactly how recent depends on how active that market is: a fast-moving market might only need the last few months, while a slow or thin market can force an appraiser to look back further just to find enough real sales to work with.
How Adjustments Work
Comps are almost never identical to the subject property, so a straight average would be misleading. Instead, an appraiser adjusts each comp's sale price up or down for the differences: add value for an extra bedroom the comp lacks, subtract value for a garage the subject property doesn't have, adjust for a renovated kitchen, a pool, or a bigger lot. Every adjustment is tied to a dollar amount and shown in the report, not just guessed at. The result is a set of adjusted values that should land in a tight range if the comps and adjustments were done right.
Comps for Pricing vs. Comps for Appraisal
An agent building a pricing strategy has more room to work with. A comparative market analysis can pull in active listings to show current competition, pending sales to show where the market is heading, and closed sales to anchor the number, all to help a seller pick a smart list price. An appraiser doing a report for a lender has a narrower job: confirm the home secures the loan amount using solid, closed, arm's-length sales, because a lender is relying on that number to protect real money.
Why Comps Still Matter If You Get a Direct Offer
Even a fast, direct offer should be built on real comps, not a guess. With Cash Flow Deals, you compare the Fast Cash Offer, where we buy your house as-is and close, and the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. You choose. Both offers start with sold-comp data that helps you understand your home's value in its current condition. The number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens. We cover repair costs, and we figure out a way, so nothing comes out of your pocket. With Premium, only what the buyer's lender requires gets fixed, with repair costs settled from the sale proceeds, from our share; with Fast Cash, we buy as-is and you make no repairs. If the Premium buyer's loan falls through, that is our problem, not yours, and you can still choose the Fast Cash Offer alongside the Premium Cash Offer, with Fast Cash at its own number.
Common questions
How far back do comps need to be?
There's no single fixed rule. Most appraisers try to stay within the last several months, but the exact window depends on how many sales that specific market has had. A slow or thin market can force a wider time window just to find enough usable data.
Can active listings count as comps?
Not for an appraisal. Active listings are asking prices, not confirmed sale prices, so they show up as context in an agent's pricing conversation, not as evidence in a formal appraisal report.
What happens if there aren't any good comps nearby?
The appraiser widens the search radius or extends the time window. In genuinely unique cases, an appraiser can lean more heavily on other valuation approaches, like estimating rebuild cost, instead of relying only on sold comps.
Do online home value estimators use the same comps a real appraiser uses?
They pull from similar public sale data, but an algorithm can't walk the property, see condition, or catch an upgrade that never made it into public records. That's why an automated estimate and a real appraisal can land on noticeably different numbers.

What this means for your options
Every path to selling a house has real tradeoffs.
Wait and see
Keep the property as-is and hope conditions improve. The mortgage, insurance, and upkeep keep costing money while you wait, with no set date for things to turn around.
List with a traditional agent
Standard MLS listing, typically 5-6% in commission, and a financed buyer whose deal depends on appraisal, inspection, and lender approval — any of which can fall through after weeks on market.
Sell to Cash Flow Deals
Two offers for your house, Fast Cash or Premium Cash, and you choose. Cash: Cash Flow Deals buys the house as-is and closes. Premium: More money. A pre-approved FHA or conventional buyer we already have buys directly from you.
